Review on Munchkin Miracle 360 Cup - 24 Ounce - Blue: Efficient and Easy-to-Use Drinking Solution by Donald Gore

Had purchased Munchkin Miracle 360 adult cup in October 2019. I really liked it, but now after 3 months we have a leak. This little white gasket has stretched and twists when you put the cap on. causing it to expire. I just assumed that I could buy a replacement part like you can buy baby carriers. I contacted the company, they asked for a photo. but no answers yet. I can't find a replacement by searching. without it, the cup is useless. I really thought it would last longer than a few months. Edited January 30th 2020 After contacting the company they told me they do not make replacement parts for this adult Munchkin Miracle 360 cup. Now I have a useless cup. Just ask. I have had this mug for 3 months and it is now unusable.
